Abstract
This study was carried out to determine some spermatological parameters and hematological characteristics of the B. grypus (H, 1843) in the spawning season. Investigation was performed using 20 B. grypus males captured from Atatürk Dam Lake. Milt and blood samples were col-lected and evaluated daily in sampling day. In collected milt, the mean values of milt volume (μL), the percentage of motile spermatozoa (%), duration of motility (s), spermatozoa concen-tration (x109/mL) and pH were 886.00 ±78.76, 71.25 ±4.56, 115.10 ±6.19, 10.61 ±1.67 and 8.13 ±0.45, respectively. The blood parameters of B. grypus males were 30.01 ±4.11, 2.05±0.07, 7.72 ±0.11, 147.27 ±4.93, 38.98 ±2.61, 26.47 ±0.84 and 29.45 ±0.75 for WBC (x103/mm3), RBC (x106/mm3), Hb (g/dl), MCV (μm3), MCH (pg), MCHC (%) and PCV (%), respectively. Milt volumes in 8 year old fish were significantly higher than those in 5, 6 and 7 year old individuals (P
